ANALYSIS OF ASH AND MINERALS - UMass

4. Analysis of Ash and Minerals . 4.1 Introduction. The "ash content" is a measure of the total amount of minerals present within a food, whereas the "mineral content" is a measure of the amount of specific inorganic components present within a food, such as Ca, Na, K and Cl.Determination of the ash and mineral content of foods is important for a number of reasons:

Protein aggregation - Wikipedia

Protein aggregation is a biological phenomenon in which intrinsically disordered proteins or mis-folded proteins aggregate (i.e., accumulate and clump together) either intra- or extracellularly. Mis-folded protein aggregates are often correlated with diseases. In fact, protein aggregates have been implicated in a wide variety of disease known as amyloidoses, including ALS, Alzheimer's ...

Sieve analysis - Wikipedia

A sieve analysis (or gradation test) is a practice or procedure used in civil engineering and chemical engineering to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.
